Abstract
An automatic water faucet apparatus includes a faucet, a detection unit, a hot water storage tank, a first ultraviolet irradiation unit, a display unit, and a control unit. The hot water storage tank heats water supplied to a water supply channel by using a heater, which is not illustrated, and stores hot water. The hot water storage tank is provided inside the faucet and heats water supplied to a second water supply channel. The first ultraviolet irradiation unit disinfects (sterilizes) the hot water stored in the hot water storage tank by irradiating the hot water with ultraviolet rays. The first ultraviolet irradiation unit includes an ultraviolet lamp disposed inside the hot water storage tank, and irradiation of ultraviolet rays to the hot water stored in the hot water storage tank and stop of the irradiation are controlled by the control unit.
